Determine blocking sessions and blocked sessions in 9iR2

Hi,
Running 9.2.0.7 on Solaris 2.
We are trying to develop a query that can show us the blocked sessions and the session causing it. I have one working for 11 but for 9i, its a little more trickier. I am running these two so far:
select s1.username || '@' || s1.machine || ' ( SID=' || s1.sid ||
       ' ) is blocking ' || s2.username || '@' || s2.machine || ' ( SID=' ||
       s2.sid || ' ) ' AS blocking_status
from gv$lock l1, gv$session s1, gv$lock l2, gv$session s2
where s1.sid = l1.sid
   and s2.sid = l2.sid
   and l1.BLOCK = 1
   and l2.request > 0
   and l1.id1 = l2.id1
   and l2.id2 = l2.id2;
select do.object_name,
       row_wait_obj#,
       row_wait_file#,
       row_wait_block#,
       row_wait_row#,
       dbms_rowid.rowid_create(1,
                               ROW_WAIT_OBJ#,
                               ROW_WAIT_FILE#,
                               ROW_WAIT_BLOCK#,
                               ROW_WAIT_ROW#)
from gv$session s, dba_objects do
where sid = 543
   and s.ROW_WAIT_OBJ# = do.OBJECT_ID;Reason I need this is that lately we have been getting a lot of DEADLOCKS and we want to determine why this is happening a lot now and we want to start with who it is and what objects are causing it....any suggestions?

There are a few critical pieces to interpreting a deadlock trace file. First, to be clear, you're getting ORA-00060, not ORA-04020 (which is a library cache deadlock), correct?
If so, the tracefile will contain a deadlock graph. This will show the type of enqueue involved (TM or TX are the likely candidates), and the modes that locks and requests are being made.
Then, there's the SQL which encountered the deadlock, and finally, the other SQL involved in the deadlock.
All the above information is in the deadlock trace file.
Using it, you ought to be able to determine root cause of the deadlock.
If you need help understanding it, post here. If you post the deadlock graph, make sure you use code tags, or it will be unreadable.Yes we are getting the ORA-00060. This is what we get exactly from the AppTeam from the App:
Available exception message: iims.ge.common.exception.IIMSTechnicalException : ORA-00060: deadlock detected while waiting for resourceFrom our latest Deadlock occurence we got a LMD Trace file generated. We can see the DeadLock graph and its SQL. We the enqueue of TX and it's modes. Basically everything you asked for we see it in the trace file. What we want to see is what is causing it or who is so we can fix it. Maybe I am not reading the trace file correctly. I appreciate your assistance in helping me interpret the trace file. As requested, here is the trace file.

GV$SESSION and V$SESSION | Find who is connecting

Any one please brief what is the diff b/w
GV$SESSION and V$SESSION
and what is the use os both...
Can we find the user who is connecting to the oracle server using gv$session view.
Oracle Version is 9i R2
OS is Solaris 9

You can find the users connecting to each node if you query the v$session. You must be aware of the node you are connecting when issuing this query because the information is exclusive from the node you are connected to.
If you query the gv$session the information gathered is the same, but as you can see it reports information from all RAC participant users.
If you take a look at the dynamic views, you will find a lot of gv$ views, those are global views that can be seen from whichever instance you are connected to and it will report information about all the instances in a single query. As you can see the gv$ views include an INST_ID (instance ID) column, which declares the number of instance the information comes from.

Disconnect session and kill session

Hi
what is the difference between
disconnect session and kill session
Edited by: Pascal Nouma on 21/10/2009 16:23

Hi,
You can use the supplied package [dbms_metadata|http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/d_metada.htm#i1015856] to get the DDL for database objects, including sequences.
If you want to continue working on this query, then I think you need a CASE expression to do one thing for 0 vlaues, and another for values >0.
Something like this:
select 'create sequence '
||     SEQUENCE_NAME
||     ' minvalue '
||      MIN_VALUE
||     ' maxvalue '
||     MAX_VALUE
||      ' increment by '
||      INCREMENT_BY
||     decode      ( CYCLE_FLAG
          , 'N'     , ' nocycle '
               , ' cycle '
||     CASE
          WHEN cache_size = 0
          THEN ' NOCACHE'
          ELSE ' cache ' || cache_size
                    || ' start with '
                    || LAST_NUMBER
     END
||     ';'
from      user_sequences;You can also use DECODE instead of CASE (and vice-versa).

ME5A: blocking indicator and blocking text

Hello SAP Guru,
In ME5A, is it possible to add comments/texts directly for each purchase requisition, such as "not ready to convert", "ready to convert" etc? The requirement from business is that they want to have a PR report with indicator to state: if one PR is ok to convert or not. Since we have not set up PR release strategy, I found "blocking indicator" and "blocking text" in ME5A, but first need to go into each PR to block, then run ME5A to get these info.
Many thanks in advance for your comments/advice and with best regards-
Mengyu

Hi Mengyu,
ME5A is to List Display PR only. It is in read only mode. You cannot change anything directly form there.
Thanks,
Gordon

GR blocked Stock and Blocked Stock

Dear Experts,
In standard way in T.code MMBE which stock in Gr blocked and Blocked stock how can I see this stock document no. ( 103 and quality 321 etc. ) in which document no they come in same stock.
Pooja

Hi,
For your require ment go to the T.Code MB51 and give the Mov type , you get the documents relataed to as per Mov no.
In MMBe itself the option is there for GR blocked stock and blocked stock.

Diffrence between GR Blocked stock and Blocked stock

Dear Seniors,
Kindly tell me the difference between GR Blocked stock and Blocked stock ? in which case, we will move stock to GR blocked stock and blocked stock ??? kindly explain me please.
Regards,
JanaMM

Hi
Material can flow directly from goods receipt into consumption/usage or into the warehouse. However, It may also be placed into a blocked stock area first.
Using the stock type, you can post the material into quality inspection stock or into blocked stock. In both cases, the material is already managed in the stock. Alternatively, the material can be conditionally accepted. Conditionally accepted deliveries for a purchase order are recorded in goods receipt blocked stock (GR blocked stock).
The quantity posted into goods receipt blocked stock is not added to the inventory or managed as part of the inventory. It is only recorded in the purchase order history.
You would use goods receipt blocked stock, for example, if the vendor's certificate for the delivered quantity were missing, or if you wanted to inspect a small quantity of the material before posting the actual goods receipt.
When the conditions for acceptance are met, the material can be accepted into stock (for example, into unrestricted-use stock). The goods receipt is not valuated until this point.
If the goods are to be returned to the vendor, instead, they can be taken directly from goods receipt blocked stock. Note, however, that a return delivery is possible even if the material was already posted into stock
Blocked Stock is Valuated Stock. it is blocked for Certain reason.
Blocked stock (not usually available from an MRP perspective and no withdrawals are possible for consumption)
From blocked stock, you can withdraw only one sample, scrap a quantity, or post an inventory difference.
If you want to withdraw goods from blocked stock for consumption, you first have to carry out a transfer posting to unrestricted-use stock.
Thanks

Web session and authentification session pb with wl6.0

Hi,
I am evaluating weblogic 6.0 on windows 2000.
I have a little web application, with some URL (html, servlet...), I want to protect.
So I defined a <security-constraint> element in my web.xml
file, and I binded the logical roles with real participant in
weblogic.xml
It works very well at startup. I launch a browser, request a protected URL and the
authentification window popup. I enter valid info and I can access my URL.
Perfect.
Now I want to give the possibility to my user to terminate a session, to disconmect,
so I had a button, (disconnect) which invoque a servlet which get the current session
and invalidate it.
I checked, the session is destroyed and a new one is defined (new ID, new counter...),
but my user are still connected. It means that if I want to acces a protected URL,
I still can do it.
more strange. In both a secured and unsecured page I print the User Principal. When
I connect, the two pages print the same and right value.
But if I disconnect, the unsecured page print null(no connection for this session)
and the secured page print the principal I used to connect in the previous message.
I know this message is a little bit long, but I tried to give the cleares context.
Has anyone ancountered that kind of problem? Is there a solution.
I pass the test with netscape 4.76, netscape 6.01, Internet Explorer 5.50. I got
the same behavior each time...
Thanks
Nicolas

If you use a Form to authenticate then the browser is unaware of the
username and password. The PetStore demonstrates how it's done in

Hi John,
thank you for your answer. It confirmed my first guess, that the
browser keep the secret info and send them back to the server.
The server does not make any attachment with the current session.
But you talk about a "ServletAuthentication" example which presents theway to bind
the login info in the session. I have not found this servlet, in weblogic6.0 distribution
or J2EE API.
Can you give me the exact reference of this servlet.
Thank you for your help.

Nicolas,
It is my understanding that the authentication information for this
scenario
(ie HTTP BASIC authentication) is not contained in the session -- it is
maintained by the browser and resent with every request. That is why
invalidating the session makes no difference. If you have a HTTPsnooping
utility you will see the "Authorization" information (albeit encodedusing
BASE64) present in the requests from your browser to the server.
FYI: I've noticed that by using the ServletAuthentication class tomanually
perform authentication, it DOES in fact store the authentication info in
the
session. There is a "done()" method in this class which removes thisinfo
from the session (ie performs a logout).
If this link reproduces properly, check it out -- it's a good simple
explanation of what's going on:

Stateful session and stateless session

i want to use session pool, but in document being stateful session or stateless session are one of standards.
i do not understand the difference of them. who can tell me something about this?
thanks! and the session we commonly used is stateful or stateless ?

A stateful session is one that must maintain a state across requests; such as one that may require package states and the like. As such, it cannot be reused by other requests until it is completely finished.
On the other hand, a stateless session is one that performs somewhat like a singleton action (statement cache for example) which, upon completion, can be reused in the pool for any other request as it does not require the state to be maintained.
The most commonly used depends on the application, but I would say stateless is more common as it's used for performing small simple things (queries or small transactions) without requiring procedural-type processing overhead.
Not sure if that description really helps you though.

Scope of component session and http session

Hi,
I wish multiple iviews to share the same information. I am unsure however of the scope of portalcomponentsession, as opposed to http session. I have read the docs, and they are unclear as to the life and scope of these 2 sessions within portal. Which one is tied to the user? And which one is available over multiple iviews.
I would appreciate any help with this
Thanks
Mariana

Just for explanation: If you give ten points (they call it blue, my eyes say black), this star is marked in the overview and somehow displaying "solved". In addtion, if you have marked a question as question, you can mark it as answered. As long as you don't do one of both things, you can reward points (2, 6) also in between without trimming your chances to get additional answers.
> I did not de-mark the question,
> I just replied to the post.
When you initially opened the thread (that was no reply), it <i>seems</i> that you've de-marked this thread as question (the standard is: it is a question).
Anyhow, some people seem to have made the experience that they definitely did not de-mark the thread as question, but it wasn't marked as question, anyhow.
In this case, a short and friendly mail to [email protected] with the problem stated and alink to the thread concernced will help to repair everything...

Although browser.sessionstore.resume_from_crash = false, it still is restoring session and even session which where password protected! how to solve

In the config browser.sessionstore.resume_from_crash is set to false, However when restarting FF all sessions can be restored by pressing the button session restore on the home page.
'''It restores also password protected sessions without asking for any password! This is unacceptible!'''

Oracle portal session and pl/sql

Hi all i use portal v.10.1.2.2.0 and i would like to play with a session variable. all i do is
grant execute on wwsto_api_session to myportal from portal schema. and then i want to do
l_store := portal.wwsto_api_session.load_session (p_domain, p_sub_domain);
l_store.set_attribute ('myname', 'name');
l_store.save_session;
1) i do not know what is the p_domain, p_sub_domain
2) when i do wwsto_api_session.get_sub_domain and wwsto_api_session.get_domain i get an error.
How can i read and write to a variable session in oracle portal? to to like java set session and get session?
Thank you in Advance,
Antonis

How can i read and write to a variable session in oracle portal? to to like java set session and get session?Hi,
You may want to see the wwsto_api_session here in [Portal APIs|http://www.oracle.com/technology/products/ias/portal/html/plsqldoc/pldoc1012/index.html].
"Working with the session object
The general procedure for working with the session object is:
1. Load the session object, with an appropriate domain and sub-domain combination, using the load_session method.
2. Manipulate the content of the object using the set_attribute methods, or just access its content using the get_attribute methods.
3. Force these changes to be saved, using the save_session method.
Typically this sequence occurs within the scope of one client routine that extracts and/or sets all of the client states. For example:
declare
l_store portal30.wwsto_api_session;
l_date date;
begin
l_store := portal30.wwsto_api_session.load_session ('PORTAL', 'TEST');
l_store.set_attribute ('LAST_ACCESSED', sysdate);
l_store.set_attribute ('USERNAME', 'SMITH');
l_store.set_attribute ('COUNRTY_CODE', 1);
l_store.set_attribute ('LOCATION', 'US');
l_store.set_attribute ('LAST_LOGGED_ON', sysdate);
l_store.set_attribute_as_string
('OFFICE_LOCATION', 'CALIFORNIA', 'US', 'STRING');
l_store.save_session;
end;
The login session that creates the session storage object is defined by wwctx_api.get_sessionid. "
ref: wwsto_api_session for Portal 10.1.2
then, look for the functions for getting attributes as number, varchar2, string or index, etc. in the above link.
hope that helps!

Difference GR blocked and blocked stock

Hi Experts
can u please tell me the difference between gr blocked stock and blocked stock.

hi
>block stock
the block stock means the stock is in ur inventory and block for some special reason like reservation or any other reson
>gr block stock
gr block stock is the stock came and blocked for QM inspection before doing actual GR
means the stock will be in our premises but not of our liability
When we have some issues in the received stock and we do not want the quantity to be considered in the inventory the we can maintain the stock as GR Blocked stock.
It is only recorded in the purchase order history. This stock is NOT valuated.You can display goods receipt blocked stock from two viewpoints:
1.Goods receipt blocked stock for a material (at plant
level)
2.Goods receipt blocked stock for a purchase order item
hope it clears
regards
KI
